Interest is calculated based on an annual interest rate, and is calculated either as simple interest or compound interest. For simple interest, you multiply the loan amount by the annual interest rate and then divide the interest by 12 to arrive at a monthly interest rate. For compound interest, the principal balance on which the interest is calculated is reduced each time a payment is made. The amount of interest changes with each payment since the interest is recalculated on a constantly changing loan balance. Fortunately, loan calculators are available on the Internet that enable you to experiment with borrowing scenarios, and these calculators compute the interest for you. Even better, you can use the QuickBooks Loan Manager to calculate compound interest and show you how much of each payment represents principal and interest. A number of calculators are available on the Intuit website: http://accountant.intuit.com/practice_resources/calculators/index.html  Enter the liability account where the loan balance is recorded.
